Re: [dtc] Get rid of libdt.c

So, like, the other day David Gibson mumbled:

libdt.c was an attempt at creating a device tree handling library
within the dtc codebase.  However, it was never even close to
completion, and is entirely obsoleted by it's spiritual descendent,
libfdt (currently a separate package).  This patch, therefore, removes
libdt.c entirely, along with its only reference in the Makefile, an
unused variable.

Signed-off-by: David Gibson <redacted>

Applied.

Thanks,
